Advances in Constructional Engineering

Ancient buildings often suffer from wall hollow drumming. Traditional restoration methods can cause irreversible damage to the walls. Drilling and grouting technology, which relies on its minimally invasive nature, is the preferred solution for repairing ancient building walls. This method uses breathable polymer mortar as the grouting material, which not only has excellent permeability but also strong bonding strength. It effectively improves the water vapor circulation inside the walls, preventing issues like dampness and cracking after restoration. By optimizing grouting equipment, pressure control, and slurry mixing ratios, and employing techniques such as gradient grouting and dynamic pressure adjustment, the mortar can be more evenly distributed in the hollow areas, enhancing both the effectiveness and longevity of the restoration. Practical engineering applications have shown that the optimized process significantly enhances the restoration results, making it a key technology with significant promotion value in the repair of hollow drumming in ancient building walls.
